DIY Bop It: How to Record and Play Your Own Voice Commands on a Classic Toy

Question:

How can I modify the sound chip of a Bop It toy to record and play my own voice commands?

I have a Bop It toy that I want to customize with my own voice commands. I have opened the toy and examined the circuit board, but I am not sure how to access and change the sound chip. I want to avoid damaging the toy as much as possible. What are the steps and tools I need to replace the original sound chip with a recordable one? What are some tips and precautions I should follow? I have attached an image of the toy for reference. It is a specific model that I want to keep. Thank you for your help.

Answer:

Bop It is a popular electronic game that challenges players to follow a series of voice commands, such as “bop it”, “twist it”, or “pull it”. The game is fun and addictive, but what if you want to make it more personal and unique? What if you want to hear your own voice instead of the default one?

In this article, we will show you how to modify the sound chip of a Bop It toy to record and play your own voice commands. This is a DIY project that requires some basic soldering and electronics skills, as well as a few tools and components. We will also provide some tips and precautions to avoid damaging your toy or injuring yourself.

Before you start, you will need the following items:

  • A Bop It toy (we are using the model shown in the image below)
  • A screwdriver
  • A soldering iron and solder
  • A wire cutter and stripper
  • A recordable sound module (such as [this one](https://www.amazon.com/Recordable-Sound-Module-Buttons-Seconds/dp/B01N0J8QSZ))
  • A speaker (preferably the same size and impedance as the original one)
  • A battery holder and batteries (optional, if you want to power the sound module separately)

    Step 1: Open the toy and locate the sound chip

    The first step is to open the toy and find the sound chip. To do this, you will need to remove the screws on the back of the toy and carefully pry open the two halves of the case. Be careful not to damage any wires or components inside.

    Once you have opened the toy, you should see something like this:

    The sound chip is the black rectangular component labeled U2. It is responsible for storing and playing the voice commands. You will need to remove it and replace it with the recordable sound module.

    Step 2: Remove the sound chip and the speaker

    To remove the sound chip, you will need to desolder it from the circuit board. To do this, you will need to heat up each pin of the chip with the soldering iron and gently pull it out with a pair of tweezers or pliers. Be careful not to damage the circuit board or any other components.

    You will also need to remove the speaker, which is the round component labeled SP1. It is connected to the circuit board by two wires, red and black. You will need to cut these wires and strip the ends.

    Step 3: Connect the recordable sound module and the speaker

    Now that you have removed the sound chip and the speaker, you will need to connect the recordable sound module and the speaker to the circuit board. The recordable sound module has four pins: VCC, GND, REC, and PLAY. You will need to solder them to the corresponding pads on the circuit board, as shown in the diagram below:

    The VCC and GND pins are for power supply. You can either connect them to the same battery that powers the toy, or use a separate battery holder and batteries. The REC and PLAY pins are for recording and playing the voice commands. You will need to connect them to the pads that were previously connected to the sound chip, as shown in the diagram.

    The speaker has two wires, red and black. You will need to solder them to the same pads that were previously connected to the speaker, as shown in the diagram.

    Step 4: Record and test your voice commands

    Now that you have connected everything, you are ready to record and test your voice commands. To do this, you will need to follow the instructions of the recordable sound module. In our case, the module has two buttons: one for recording and one for playing. To record a voice command, you will need to press and hold the record button and speak into the microphone. To play a voice command, you will need to press the play button.

    You can record up to 10 seconds of audio for each voice command. You can record as many voice commands as you want, but you will need to remember the order in which you recorded them. For example, if you want to replace the original voice commands with “bop it”, “twist it”, and “pull it”, you will need to record them in that order.

    To test your voice commands, you will need to turn on the toy and press the play button on the sound module. You should hear your voice command. Then, you will need to perform the corresponding action on the toy. For example, if you hear “bop it”, you will need to bop the toy. The toy should respond with a sound and a light. If you perform the wrong action or fail to respond in time, the toy will make a buzzer sound and the game will end.

    You can repeat this process until you are satisfied with your voice commands. You can also adjust the volume of the speaker by turning the potentiometer on the sound module.

    Step 5: Close the toy and enjoy

    The final step is to close the toy and enjoy your customized Bop It game. To do this, you will need to fit the sound module and the speaker inside the toy case. You may need to cut some plastic or use some tape or glue to secure them. Be careful not to damage any wires or components inside.

    Once you have fitted everything, you will need to close the toy case and screw it back together. You may also want to decorate the toy with some stickers or paint to make it more unique.

    Congratulations,

you have successfully modified your Bop It toy to record and play your own voice commands. You can now enjoy playing the game with your own voice and challenge your friends and family. Have fun and be creative!
